[0069] Reference Figure 14 , the coffee powder bin assembly 4 and the water outlet seat assembly 3 are connected by a sliding buckle mechanism 31, and the detachable connection is realized through the sliding buckle mechanism 31;

[0070] The sliding buckle mechanism 31 includes a pressing member 311 and a sliding member 312, and the pressing member 311 drives the sliding member 312 to move horizontally through vertical movement;

[0071] The sliding member 312 is provided with a convex buckle 3120, and the coffee powder bin assembly 4 is provided with a buckle groove 45 that cooperates with the convex buckle 3120. The coffee powder bin assembly 4 is structurally connected to the water outlet seat assembly 3 through the convex buckle 3120 and the buckle groove 45;

[0072] When disassembly is required, the pressing member 311 is touched downward, and the pressing member 311 drives the sliding member 312 to move horizontally away from the coffee powder bin assembly 4, and the convex buckle 3120 moves away from the buckle groove 45, so that the coffee powder bin assembly 4 is separated from the water outlet seat assembly 3.

[0073] Furthermore, the pressing member 311 is provided with a first inclined surface 311a, and the sliding member 312 is provided with a second inclined surface 312b that cooperates with the first inclined surface 311a; through the cooperation of the first inclined surface 311a and the second inclined surface 312b, the vertical movement is converted into horizontal movement;

[0087] Two relatively arranged second openings 4412b are provided on the second flange 4412;

[0088] The first openings 4411a and the second openings 4412b are arranged staggeredly;

[0089] Thus, the water diversion channel 441 is arranged in a certain circuitous manner, prompting the coffee to flow circuitously and better slowing down the flow rate of the coffee.

[0090] Furthermore, the base assembly 1 further includes a battery 15, and the battery 15 provides electrical energy for electronic components such as the booster pump 14 and the heating tube 12;
